Hidden field values not accessible on server side while posting from child page to parent page using javascript

No it doesn't work.  values are not present in Hidden field.

Please modify the code in page load and try it.

if (!IsPostBack)

string s = hdnField.value; // Hidden field value is empty at this point

Hi

I was busy of late.

Ok. I got the general idea of what u said. It  it's only a single page, then it's fine. But in my case, after the parent page

javascript function executes, the hidden field value(s) are populated into the listbox of parent page. That's fine. But Still I am unable to access this hidden field values at the page_load or a button click of the parent page.

In the parent page

if (page.ispostback)

{

  string s  = hdnField.value; // Hidden field value is empty at this point

}

I tried taking the values into a textbox. But It doesn't work. And in any case I do not want to use a Session variable

.It defeats the very idea of using a client script.....

Can u suggest a better alternative?

thanks

The concept is simple .I have a text box and I am saving the text box value into hidden field variable inside javascript function.So now this value inside hidden field is available for all the sub pages. You can retrieve the value in 'page load' of any page.

I showed you the concept of hidden field using textbox. You can use any other controls to to do this.

In your case try to retrieve the value of hidden field in page load.

Hi

I went through ur code. But it isn't working. What is the use of the textbox? After the postback from the child page,

the hidden field(located in parent page) values is lost.

I need to have these values persisted in my parent page.

Can u explain in detail?

thanks

You can get the hidden field value in server side in following way.Use the same lgic for your application

Inline code section:

//declare the fidden field inside body of html

Javascript function.

function LoadFiles(RecordStatus)

{

var LastDays = document.getElementById("txtLastDaysFiles").value; // txtLastDaysFiles is the Id of a text box
document.getElementById("hidlastday").value=LastDays; // assign the lastdays value to hiddenfield

}

codebehind:

private void displayArchiveDetails(Int32 PageNumber)

{

string strLastDays = "";
 
  strLastDays = hidlastday.Value;

}
